PUMP.

SPECIFICATION forming part of Letters Patent No. 445,577, dated February3, 1891.

ipplication filed J'uly 17, 1890. Serial No. 359,052; (No model.)

T all whom t may concern.-

Be it known that I, JOHN W. WADswoRTH, a citizen of Allegheny city, inthe county of Allegheny and State of Pennsylvania, have invented certainnew and useful Improvements in Pumps; and I do hereby declare thefollowing to be a full, clear, and exact description ol' the invention,such as will enable others skilled in the` art to which it apro pertainsto make and use the same.

My invention relates to an improvement in pumps, and more particularlyto a pump adapted for removing or drawing off liquid, such as beer froma barrel or other receptacle; and it consists in certain novel featuresof construction and combinations and arrangements of parts, ashereinafter set forth and pointed out in the claim.

In the accompanying drawings, Figure l is a longitudinal sectional Viewof the device. Fig. 2 is a detached view of the intermediate controllingmechanism. Fig. 3 is a horizontal sectional view of the intermediatecontrolling mechanism.

A represents the barrel of the faucet; I3, a pump, and O an intermediatecontrolling mechanism, to which latter a spigot or outlet is attached,as explained hereinafter.l The forward end of the barrel of the faucetis made slightly tapering, as usual, to enter the receptacle containingthe liquid to. be withdrawn, and at a point near its rear end saidbarrel A is provided with an ordinary turning-plug` or stop-cock D. rlherear end of the barrel A is enlarged somewhat and provided with aninteriorly-screw-threaded socketD for the recept-ion of asimilarly-threaded stem D2, projecting from the intermediate valve orcontrolling device O, which latter is provided at its other end with aninteriorly-scre w-threaded recess C for the screw-threaded end of thepump B.

The device C comprises a barrel 1, a valvechamber 2, outlet-ducts 3, anda spigot at. The valve-chamber 2 extends downwardly to a point at aboutthe center of the barrel 1, where it communicates with an inlet-port 5,which latter extends through the stem D2, having at its end a strainer6. In proximity to the 5o juncture of the valve-chamber 2 and theinlet-port 5 a valve-seat 7 is made, upon which a valve S is located andadapted to normally close communication between the valve-chainber 2 andinlet-port ,the stem 9 of thisvalve projecting a short distance into thevalvechamber and adapted to engage a pin 10, eX- tending across saidchamber, and thus limit the play'of the valve o. A duct l1, whichcommunicates at its lower end with the recess C', passes diagonallythrough a portion 6o of the barrel 1 and terminates at its upper endjust above the stem 9 of the valve S, thus connecting the valve-chamberwith the pumpbarrel. Immediately above the termination of the duct 11 isthe valve-chamber 2. Said 65 chamber is bored to produce a valve-seat12, upon which a valve 13 is located. The stem lf-l of the valve 13projects upwardly, and is adapted to enter a recess in a cap 15, screwedinto the top of the valve-chamber, whereby 7o said valve 13 ismaintained in proper position.

The outlet-d ucts 3 are made in anges 16 at opposite sides of the barrel1, said ducts communicating with the valve-chamber at points above thevalve 13 and terminating at their 75 lower ends in a recess 17 in theunder side of the barrel l. Surrounding this recess is aninternally-screw-threaded flange IS for the reception of thesimilarly-threaded upper end of the spigot al.

The pump-cylinder is connected with the valve mechanism, as previouslystated, and provided with a piston and piston-rod of any approvedconstruction, which latter passes through the head 19 of the pump, andis pro- 85 vided on its free end with a handle 20. The head 19 of thepump is formed with a slight depression to produce a shallow chamber 2l,with which a perforation 22 in the periphery of the cap is adapt-ed tocommunicate, a small 9o spigot or outlet-port communicating with saidperforation. Opposite the spigot or outletport 22 a knob 23 is securedtothe cap, whereby to turn it. Vhen the head 19 is screwed upon thecylinder of the pump to its fullest extent, the perforation 22 will bepartially closed; but by turning the head 19 more or less the size ofsaid perforation may be varied and the outlet of air from thepump-cylinder varied.

When the piston is withdrawn, a partial vacuum will be produced betweenthe Valves IOO 8 and i3, causing the former to be raised and the latterto remain closed. Thus 'communication will be opened between thevalve-chamber and the inlet-port 5, whereupon liquid will {iow into saidchamber and from thence through the ductI 1l into the pump-cylinder andll the vacuum produced therein by the withdrawal ot' the piston, the airbehind said piston having escaped through the spigot or outlet-port 22.The pump being now filled with liquid, the piston is propelled and theliquid forced back again through the duct l1 into the valve-chamberbeneath the valve 13, whereupon said valve 13 Will be raised by thepressure ot' the liquid and open communication between the valve-chamber2 and outlet-ducts 3, thus permitting the liquid to ilow to the spigot4.

-By means of the apparatus above described beer, 4cider, or other liquidmaybe easily and quickly withdrawn from a keg or barrel without thenecessity of admitting air to the barrel, thus relieving the liquid fromany injurious effects produced by the contact therewith of air.

Slight changes might be made in the dctails of construction withoutdeparting from the spirit or scope of my invention. Hence I do not wishto restrict myself to the precise details of construction hereindescribed; but,

l Having fully described my invention, what I claim as new, and desireto secure byLetters Patent, is-

The combination, with a faucet and pump, of an intermediate controllingmechanism connected with said parts, this controlling mechanism having aspigot at one end, a main duct leading through from the faucet to thepump, valve mechanism in said duct, and ducts leading from this valvemechanism around the main duct and terminating in the spigot,substantially as set forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing Witnesses.
